BRAGING MEANS FOR SHAPER RAMS Filed March 13 1930 2 Sheets-Sheet 1 gigZ. INVENTOR ATT O'RN EY5 Patented Oct. 11, 1932 UNITED STATES FFICE BRACiING MEANS FOR SHAPER RAMS Application filed March 13, 1930. Serial No.435,621.

This invention relates to that class of metal working machines known asdraw-cut shapers and particularly to those machines designed for veryheavy work and employing a reciprocable ram supported at one end withits tool carrying end in overhanging relation to the work.

In this type of machine it has been found that there is liable to be aslight deflection of the ram under the very'heavy strain imposed thereonduring the cutting stroke, which deflection will aflect theaccuracy ofthe work, and the object of the present invention is to eliminate, inmachines of this character, any possibility of such deflection. It isalso an object to provide adjustable means for compensating for wear sothat after long use, there will be no deflection of the ram due to suchwear, and to provide an arrangement whereby such adjustment may bequickly and easily effected and will 00-- operate with either a fixed orrotatively adjustable tool carrying head on the ram, to

effect such accurate adjustment.

With the above and other ends in view, the

invention resides in the matters hereinafter Figure 1 is a sideelevation of a machine illustrative of an embodiment of the presentinvention;

Fig. 2 is an end elevation of the ram and adjacent parts;

Fig. 3 is a longitudinal section substantially upon the line 3- 3 ofFigure 2; and

Fig. 4 is a transverse section substantially upon the line 4l4 of Figurel.

While the present invention is shown as applied to a draw-cut shaper ofa particular construction such as that shown in my pending applicationfiled January 25, 1928, Serial No. 249,282, it will be understood thatthe same may be applied to othershapers of this or of the push out typedesigned for heavy work and including an overhanging ram subject'toheavy lateral strains during the cutting stroke of the cutting toolcarried by the free end thereof. j j p In the drawings, Aindicates asuitable base for the machine, B the upright pedestal or body on thebase provided with suitable bearings, not shown, at its upper end for ahorizontally reciprocable ram 0 which ram is supported in said bearingson the pedestal at one end only, with its free end provided with acutting tool carrying head indicated as a whole by the letter D inoverhanging relation to a work supporting table E. This work table issupported by a supporting frame F extending therebeneath, said framebeing secured to a vertically movable rail G guided by vertical guides Gon the pedes talB, and in turn carrying a horizontally reciprocableapron H which is adapted to be reciprocated upon and guided by guides Hon said rail G in its horizontal movement transversely of said ram, saidtable being secured to and movable with said apron relative to saidsupporting frame F and rail G, the vertical face of said apron extendingat right angles to the upper face of the table to properly locate work Isecured in place upon the'table, The rail Gr and supporting frame F arerigidly supported and vertically 7 adjusted by means of verticalsupporting screws J and J mounted on the base A with the screws Jsupporting the rail and the screws J beneath the free end of the frameF.

As fully disclosed'in said applicationabove so referred to, motion istransmitted from the drawing parts of the shaper for moving said tableeither vertically or horizontally with I either a continuous orintermittent feed motion, such motion transmitting meansbeing indicatedin part as carried by said rail and in part, as mounted upon theadjacent part of said pedestal, but as said motion transmittingmeansforms no part of the present invention, the sameis not fully shown inthe accompanying drawings or described herein. To providean absolutelyrigid abutment or backing for the projecting end of the ram so that itcan not yield in the slightest under the extremely heavy-strains imposedthereon duringthe cutting stroke of the ram, a cap member or head 1 isbolted or otherwise rigidly secured to the upper end of the pedestal B,or if foundpracticable to do so, maybe formed integral with thepedestal, and this or outstroke of the ram .said holder may cap memberis formed with a laterally proecting portion or nose 2 which extendsparallel with and in spaced relation to the upper The tool carrying headD is ofthe usual construction,it being attached to the reduced"'andscrew-threaded end 0? of the ram by" a split and internally.screwthreaded collar "6 on the 'head'so that this head may be adjustablyrotated upon the ram to set the toolf at an angle or swing it from side'to sidefor performing certain operations, and said tool is securedwithin a sock et member g which is pivotally supported in a slot in thehead by means of apivot pin h so that upon the idle swing to relieve thetool. upon that stroke, the swinging of said holder in an oppositedirection or upon the working stroke of the ram, being limited to causethe tool to vengage the work and take a cut therefrom, all being A'constructed and arranged inan old and well known manner.

- Seated upon and rigidlysecured inany suitable manner to the upper endof the head D is a seat block 3 and this block is formed with anupperseatingv surface t which is curved transversely of the head concentricwith the axis about which the head is rotated upon theend-of the ramforpurposes of adjustment. A; lower wedge membery5 .is formed at itslower side with a correspond- "ingly curved seating surfaceto seat uponthe surface 4 of the block 3, and this wed e memberis provided withend.lips 6 and? to en- 'gage the ends of the block 3,the lip6 beingp'rovidedwith a slot 8 curved in the vdirection of its length andthrough which slot a bolt 9 extends and is screwed into a screwthreadedopening in the adjacent end of the block 3. iThe seat block 3 maytherefore swing with the head D relativeto'the wedge member 5 whensaid'head is adjusted rotatively upon the ram, and the'block and wedgemember then locked in their relative positions by means of the bolt 9. a

The upper fiat's'urface of the wedge memher 5 isinclined in thedirectionofits length or longitudinally of the ram and seated upon thisinclined surface is an upperwedgemem- 'ber 10 having a'lower surfacewhich isfinclined in the direction of the length of the member to seatupon the correspondingly inclined upper surface; of thewedge, 5, saidmember 10 being ofxgreater'lengththan. the

two Wedgemembers may beshifted relatively longitudinal direction, thewedge 10 bein thuad iv n in, bet e the Wedge 5 and a wearplate 14secured upon the lower face of the noseor abutment member 2 extendingsubstantially tliefull length of said face and securedin placebetweenguide plates 15 by screw bolts 16 passing therethrough and into theedges iofjsaid plate 14,said guide plates being secured torthe sideedges of the nose member by screwbolts, 17.. These guide plates are ofawidth to extend down into contact withthe sideedges of the wedge members5 and '10, thus forming a guide channel or way within which the wedgesare guided as they are reciprocated therein with the tool carrying headupon reciprocation of the ram,

These wedge members 5 and 10 thus form an adjustable bearing for thehead D upon thelower side of the nose memberi2,and wear may bequickly'compensated for byadjusting said wedgeimembers relatively, andthe nose orabutment 2f'thus forms a rigid trackfor the headD regardlessof the position to which it 'is rotatively adjusted upon the end of theram and takes the'jheavy thrust of the cutting tool during theworkingstroke, so that the possibility of theram yielding or springingupwardly under such heavystrains, is obdirection of the lateral thrustthereonfof a tool carried by said. ram'and having'a lon- Ill gitudinalguide, and av tool carrying head I carried by the unsupported endportion of said ram to move, therewith and guided by said guide ,incontact with said member to prevent said ram from yielding laterally inthe direction of the lateral thrust of the tool etal working machinehaving'a body and a horizontally reciprocableram supported by said bodywith its cutting tool carrying end projecting laterally from saidbodyand unsupported, of a member rigidly supported saidbody and .ex endng .late a1ly t er f m,lenait y of said ram at the side of saidram-inthe direction of lateral thrust of a tool carried by said ram andextending in spaced relation to said ram and to the extreme outer end ofthe stroke of said ram, and separate bearing means carried by theunsupported end of said ram in sliding engagement with said member, saidbearing means including relatively adjustable members for expanding saidhearing means between said ram and member to compensate for wear.
